Global 6.6.7 tramp failure

[Felix Fernandes]

Hello,

I installed Global 6.6.7 on Mac OS Catalina and also on a remote system with Linux CentOS Rel. 6.9.
On the Mac, I am running Gnu Emacs 27.1.

From the release notes, Tramp should be supported but when I use helm-gtags-dwim on a remote file,
emacs reports "GTAGS not found". However on the remote system, I can issue "global -f filename.cc" on that file
and it shows that the gtags do exist.

Do I need to do something extra after installing Global 6.6.7 as exlained in the installation instructions?
Please help.

Thanks,
Felix Fernandes
